Reinstall Windows Search?

The below Application Log events happen multiple times a day, I am thinking reinstalling Windows Search will help solve the issue. Have tried many things and issue still there.

Try doing a system restore to before the problems. Something seems to make Windows Search Indexer crash.

System Restore

Unfortunately I do not know when the issues started and I have limited restore points.

Ok. What software or change have you made lately?

Hi FIrecat, eventually I just re-installed W7 and did not install Acronis. Using an alternative backup solution, all is running extremely well. Seems the lesson here is do not install products that claim to be W7 x64 compatible without doing a lot of research.
